FIELD: polymer production.
SUBSTANCE: invention relates to polyorganosiloxane synthetic area and can find use in creation of heat-resistant composites. Novel hydride functional polycyclic organosilicon polymers have general formula: (SiO1.5[YSi(CH2)2]nH)6-1500[SiO2]1-3000, where Y represents -O- and/or -CH2CH2Si(Me-)3)O- and n = 1 or 4. In particular, when Y is -O-, then n = 1 or 4, and when Y is -CH2CH2Si(Me-)3)O-, then n = 1. Method of preparing such polymers is also described. Thus obtained polymers are intended to be included in composite material compositions or for production of multifunctional organosilicon polymers based thereon.
EFFECT: increased yield of desired products under commercially acceptable conditions.
